Hypotrochoid[edit]

Original (click to view)

Reason: The picture shows an excellent example of how a hypotrochoid is constructed, and it significantly adds to its article.
Proposed caption: The construction of a hypotrochoid. As the smaller orange circle rolls around the inside of the larger green circle, the point attached by the blue line traces out a curve known as a hypotrochoid.

Question Why all the colors? Some people are colorblind, you know. Suggest making the circle gray, at least. Jeff Dahl (Talk • contribs) 06:36, 15 November 2007 (UTC)[reply]
Oppose The red hypotrochoid has a 1-pixel wiggle for a while in the beginnig. There needs to be a pause after the curve is completed. Fix this, and I'll support. --Janke | Talk 09:21, 15 November 2007 (UTC)[reply]
Oppose This certainly could be fixed up: There are lots of dithering on the background inside the grids when the background should be white; the grid lines are like the marching ants, constantly moving; the unnecessary antialiasing of the Y-axis should be removed by moving the Y-axis half a pixel either side; the antialiasing on the major grid lines should also be removed or at least made the same colour as the minor grid lines; these improvements would improve the palette used and reduce the unnecessary dithering, reducing its size. --antilived^{T | C | G} 11:04, 15 November 2007 (UTC)[reply]
Neutral, i feel it's quite laggy - would it be possible to add more frames? (although i do understand that would increase the loading times for people with poor connections in non-Western countries) --Aqwis 14:12, 15 November 2007 (UTC)[reply]
Comment I agree with most of the above comments, but I think the most important thing is a pause at the end of the animation sequence.--Here T oHelp 00:48, 16 November 2007 (UTC)[reply]
Oppose. There's too much shifting of the red line. Doesn't compare with Image:Foucault pendulum animated.gif, which is a stunning animation. SilkTork *SilkyTalk 13:25, 17 November 2007 (UTC)[reply]
